Researchers at NIST and the University of Maryland have developed a “quantum buffer” that could control data flow in quantum computers. The buffer uses entangled light beams to delay one beam while the other continues at normal speed. This allows precise timing of data streams, which is crucial for quantum computing applications like data decryption and database searching.
The buffer works by generating pairs of entangled light beams using a technique called four-wave mixing in rubidium gas cells. One beam is slowed down in a second cell, creating a delay of up to 27 nanoseconds. The delayed beam can then be synchronized with other data streams, enabling more efficient quantum computing operations.
This research builds on previous work demonstrating entanglement in multi-pixel quantum images. The new buffer system offers a compact, tunable solution for controlling quantum data flow, with potential applications in quantum communication systems and information processing.
